DAY BED AND-THE LIKE.

Application filed August 6-, 1926.

My invention relates to day beds, and the like, and, more particularly, to' that type wherein there is a main or stationary bed section and a movable or extension bed section adapted to be extended so as to bring its mattress structurein the same plane with the mattress structure of the main bed section when in use and to be supported in superimposed position over the main bed section when not in use. i

One of the objects of my invention is to provide a bed of this type which is compact, simple in construction, durable and` cheap to manufacture, and which may be used elliciently as a couch or seat when closed andl as a double bed with allof the conveniences thereof when ope'riied.v w l no'tlie'r object is topiovide compact and efficient means for raising and lowering the mattress structure of 'the main bed'section andl maintaining it in such raised position when the other Vbed section is extended, such means consisting in part of improved spring and link arrangement mounted and effective at cach end of the bed.

A further object is to provide means for automatically linking the mattress structures of the respective bed sections together in open position, such means being adapted to automatically effect disengagement o'f such sections as the bed is Closed, and effective in so linking the bed sections, as to prevent vertical displacement of theadjacent edges of the mattress structures, whereby the comfort of the user of the bed is greatly increased.

Other and further objects will become apparent as this description progresses and by reference to the drawings wherein:

Fig. 7 is a detailed view taken on line 4f-7 of Fig. 6, showing the manner of engagement of the linking parts referred to' in connection with the description of Fig. 6.

Referring particularly to the drawings, which show the preferred embodiment of niv invention, the bed may comprise a main bed section A (see Figs. 1 to Zi) and an extension bed section B. The niain bed section A comprises. an end frame at each end, each end frame having a front leg l and a rear leg' 2, both formed preferably of anglo iron, an anglo bar 3 connecting the upper ends of such legs and a flat bar 4lparallel with the bar 3 for connecting such legs at the bottom. A bar 5 at the front extends longitiulinally of the bed section to connect the sides of thecorresponding end legs together, and a similar bar (i is so connected to the rear legs 2.

A spring mattress structure is niounted for vertical n'iovement on the main bed section. This spring mattress stri'i'cture comprises coiled bed springs 7 which are suitably connected together at their upper ends in any d esired manner so as to hold them in upright operative position, the joined springs being confined within and supporting the outer or border wire or rod 8.. The bed springs 7, at their lower ends are mounted in any desired manner, preferably, on transverse bars or slats (not shown) which are secured at their ends to suitably provided longitudinal side bars 9 and 9a' which are, in turn, connected together near their ends by a cross bar 9*" (at each end). These latter named bars are preferably formed of angle iron. l y l The movable or extension bed sec-tion, at each end, comprises an end cross bar 10 connected at its opposite ends by the side members 12 and 13, and supported by a leg 11 at each end. Theses'u portingnie'nbeisare also peferety formen of angle* iert 'ne iii? spring mattress A, structure of the extension bed section'is preferably like that of the main bed section with the exception that the transverse slats (not shown) which carry the bed springs 7a may be supported directly by the side members 12 and 13, while the corresponding slats of the main bed section are connected to the independent side or longi# tudinal members 9 and 9a which are not fastened directly to the end frames of the main bed section for reasons which will become fully obvious hereinafter.

AThe extension bed section is swingingly supported upon the main bed section by pairs of parallel links 15 and 16, each end of the bed being provided with' identical pairs of such links. The upper end of each of these links is pivotally mounted to the cross end bar 10 of the extension bed section by suitably provided bearings in the form of studs or the like. The lower end of the link 15 is connected to and pivotally supported upon the cross bar l of the main bed section by being mounted'upon a protruding end of a rock shaft 17, the rock shaft 17 being the ordinary rock shaft provided for effecting simultaneous` and uniform movement of the bed section at both ends thereof. The lower ends of the links 16 are also `pivotally connected to the cross bar f1 by a suitably provided bearing which may take the form of a stud or bolt 16a.

By observing Figs. 1 and 3 it will bev seen that when the bed is lopened and the movable bed section is extended, the spring mattress structures of these twobed sections lie in the same plane, making a smooth ma tti-ess surface. as will be seen in Fig. 3, it will be noted that the spring mattress structure of the main bed section, has ybeen lowered to a. position beneath that shown in Fig. 1 to permit the extension bed sect-ion to be movedover into the position shown in Fig. 3, thus providing a compact bed .structure which may be readily used as a couch or seat when not being used directly as a bed. j

The means for raising and lowering the spring mattress structure of the main bed section during the opening ofthe extension bedsection to bring the bed to the positions shown in Figs. 1, 2 and 3 may comprise, at each end of the bed, a pair of toggles, vone toggle located at the front portion ofthe main bed sectionV and the other at therear of the same.I The rear toggles comprise a pair of toggle links 1S and 19'while the front toggles comprise a pair of links 20 and 21. The toggle links 19 and 21 are pivoted at their lower ends to a cross bar 22 which `is in turn supported` at' its ends bythe longitudinal bars 5 andl'. The toggle links 18 and 2O are pivotally connected. at their upper ends to the cross bar member 9b which carries thespring mattressrstrueture of the main bed section. The toggle .links 18 and 19 and- 20 and 21 are pivotally 'connected together as at 23 and 21 respectively, thus completing the toggle. The pair of toggles, at each end, is joined together by a toggle connecting link 25' so they will operate in unison and a movement of one toggle will cause a corresponding movement of the other. The toggle link 21 at each end is provided with an extension 21a which carries suitable means, which may be a roller-jor stud, or the like, indicated at 2lb, forengaging and riding in a longitudinal slot` 9.in the spring mattress cross bar .structure `9".

Movement of the pair of toggles at each end is effected through 4the medium of the operating link 26. This link 26 is pivotally connected to the toggle linkslSand 19 at their point of pivotal connection being carried by the pivot'23 joining these two links together at their inner ends. The swinging link 16 at each end is provided intermediate its' pivotal connections with a laterally projecting lug or pin 28,.or roller if desired, which is adapted to engageand ride in the longitudinal slot. 29 in the toggle operating link 26.

In this manner the swinginglink 16 .after a.

predetermined movement thereof is adapted toy pick up the toggle operating link 26 and move the same, together with the toggles `toE raise the spring mattress structure of the main bed section.

From the foregoing description it is seen that the following operation takes place durf ing the opening and closing movements of the bed: Assuming that thebed is in closed position as shown in Fig. 3, the sido member 12 of the extension bed. section may be grasped and moved outwardly so as to move the extension bedsection outwardly. During this movement the swinging levers 15 and 16, pivotally connected to-both the extension bed section andthe main bed section, cause the extension bed section to swing upwardly and outwardly in an uprightposition.` At the beginning of this movement of the extension bed section, and until it is moved to the position yof Figu1'e2, the pin V28 of the swinging link 16 moves along freely in the longitudinal slot 29 of the link 26, the

link 26 taking only a slightcompensating up.

ward movement about its pivot, with the result that the extension bed section is moved to the position 4of Fig. 2`before there is any movement of the pairsof toggles at each end of the bed to cause an lupward: movement of the spring mattress structure of the main bed section. Obviously, thepositiony of piek up need not be limited to the exact position of Figure 2 but may be varied according to the requirement or desire in any par-` ticular case. One purpose in providing this lost motion is to enable the `extension bed section to be moved upwardly and to a preliminary position before the spring mattress structure of the main bed section is moved,

so that it will readily clear andnot conflict with the following movement of the spring mattress structure of the main bed section during the final opening movement of the extension bed section. As the extension bed section is moved from the position shown in Fig. 2 toward the position shown in Fig. 1, the pin 28 earrieohby the link- 16 engages-the outer end of the link slot v29 so that continued movement of the link 16 will act to cause a corresponding movement of the toggle operating link 26. As this latter movement of the toggle operating link takes place, the toggle links 18 and 19 are extended` as shown in Fig. 1, this extended movement being simul taneously transmitted to the toggle links 20 and 21 through the medium of the toggle connecting link 25. As the pairs of toggle links are extended, the extension 21El ofthe toggle link 21 is moved to carry its pin or roller 21" forwardly in the slot 9c to the position shown in Fig. 1. (It this manner the ext-ended toggle link 21 `serves to additionally support the spring mattress structure and lock the same in its uppermost and open position.

In order to assist the user in opening and closing the bed, I- preferablyemploy a. pair of springs and 31 at each end of the bed. Une end of each` of these springs may be connected in any desired manner to the stationaryV frame of the `main bed section, While the otherend of eac-h spring is connected to a V-shaped member 32 as at 33 and 34. The V-shaped -member 32 is mounted upon the pivot lug or rivet 16a which carries the swinging link 16, such V-shaped member being also pinned, or otherwise securely fastened to the swinging link 16, as at 35. lVit-h this arrangement when the bed is in its closed position as shown in Fig. 3, each of the springs are under tension, the spring 30being under greater tension than t-he spring 31. During the opening movement of the bed the tension of these springs, at the beginning of this movement tend to assist. the operator in swinging the levers 15 and 16, the pressure exerted by the springs, at the beginning ol such movement tending in that direction. At a certain position during the movement of the extension bed section to the position shown in Fig. 2, the tension is removed from the spring 30 and, by the time such extension be'd section reaches the position of Fig. 2, the tension is removed from the spring 31 and again applied to the spring 30. The spring 30 being under tension in this latter position, upon further movement of the extension bed section, the spring 30 is placed under greater tension and serves thereby to cushion the further opening movement of the extension bed section. Towards the completion of this opening movement the sprincIf 31 is again placed under tension which iiirther assists 1n the aforementioned cushioning of the opening movement. Upon closing the `bed the reverse or the =foregoing operationtakes place. At the beginning of the closing operation the springs function to assist the operator in swinging the-extension bedltowar'ds closed position and at the completion of such movement they function to cushion the `closing movement in a. manner similar to the cushioning oi the opening movement.

Each bed section carries its own spring mattress structure, and, as already stated, they lie in the same plane in open position of the bed. Unless otherwise provided for, such construction would involve a break in the continuity oi" the complete and open spring mattress structure at the adjacent inside portions o the border wires 8 and 8a. This condition nould permit. an up and down or sagging movement of one border Wire and its adjacentbed springs relative to the other during movenient of the occupa-nt of the bed from one position to another on the bed, which .may cause such occupant considerable discomfort. lt is desirable to eliminate this con dition and have the spring mattress structures ofthe hed sections in their open position iorin a continuous spring surface. I provide tor this by the use of a plurality of automatically operating hook members 3G. lFach or these hook members comprise a piece of spring wire bent to a. V-shape, the closed end of the V being vformed to a hook-like shape as shown in Figs. 6 and 7. The hook portion 37 el each oi these hook devices is provided with a looped extension or lip 37u bent at an obtuse angle relative to the depending portion 3? of such hook. The bend olf the lip or guide 37 is made at a point spaced inward of the point where the. border wire 8 of the spring mattress structure of the main hed section engages the hook 37. The legs 36L of each ot' the hook members straddle the border wire 8 of the spring mattress structure of the extension bed sect-ion and pass on and over and are interlocked with and secured to adjacent bed springs 7a of t-he extension bed section as at 36 in the manner shown in Figs. -and 6, the extreme ends of the V-legs being bent around or over one ot the coils ot such bed springs in any desired manner. lith this construction, as the extension bed section is moved to open the hed, the guide or lip 37 of each hook 37 first contarts with the border Wire 8 of the spring mattress structure of the main bed section and, upon the continued movement of t-he extension bed section this guide 37u guides such border wire along its under-surface and snaps the same into the hook portion 37" to the position shown in Fig. 7. The spring mattress structures are thus locked together so that they form one continuous spring mattress surface with the same eii'ect as if the adjacent bed springs and 7a of the respective spring mattress structure were joined to form the usual full sized spring mattress structure, while, at the same time, permitting sepa-ration of these mattress structures in closing the bed. T here will be no sagging of one mattress structure away from the other. Thus, all the comforts of a full sized bed are provided. i

As the extension bed section is moved towards its closing movement and is moved upwardly, with a corresponding downward movement of the spring mattress structure of the main bed section, the hooks 36 are moved out ot' engagement with the border wire of the springmattress structure ot the main bed section, effecting disengagement of these respective spring mattress structures. Thus, it is seen that eli'ective means'are provided for automatically locking and unlocking the spring mattress structures to cause them to assume a continuous spring mattress structure in the open position of the bed, and to break such continuity in closing the bed.

It will be understood that the invention is susceptible oitvarious changes and modifications without departing from the scope and spirit of my invention as defined in the following claims.
